This loss appears owing to the high value of the fouling heat resistance and is called the thermal degradation process. It is linked to falling the heat flux transported by a heat exchanger and decreasing total efficiency of the heat unit as well as increasing costs of operation and freight costs after all. The loss of thermal power of a heat exchanger does not only depend on the fouling thermal resistance but is also strictly correlated with the thermal quantities of a given heat exchanger, among others its overall heat transfer coefficient values at various operating modes. The paper presents the aforementioned phenomena and results of the author’s own experimental studies, as well.}, doi = {10.12716/1001.15.01.18}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Marine Power Plant, Gathering of Fouling, Heat Transfer Surfaces, Heat Performance Characteristics, Ship Steam Systems' Heat Exchangers, Thermal Resistance, Heat Transfer, Heat Exchangers} }
